kinit return bug (?)

[Grau, Stephen]

If you kinit, for example, with a slash in the realm error, you get a
KRB5_PARSE_MALFORMED error, but kinit returns with a 0 return code.
In the code, it is only returning an error code if a valid instance was
parsed and it wasn't authenticated. I think it should return an error code
if it wasn't able to get a valid instance.
This is the best I could do with the diff. This is also present in 1.2.8 and
1.3-alpha2.
